Estimated revenue
A model estimate with a likely range, not a reported figure.
No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.
How this estimate is made
Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.
Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.
Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.
Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.
Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

About this app
Text from the App Store listing.
This Opioid Calculator Application is a tool for the calculation of total oral Morphine Equivalent Daily Dose (oMEDD). A particular design feature of the app is that it simplifies the calculation of oMEDD in cases where combinations of opioids are used. It is designed to provide easy accessibility and consistency to facilitate research, improve education and fill a void in the availability of reference conversion data in clinical practice. This opioid calculator is produced by the Faculty of Pain Medicine of the Australian and New Zealand College of Anaesthetists (FPM ANZCA) which is the peak body responsible for the education, training, continuing professional development and maintenance of standards of clinical practice for specialist pain medicine physicians in Australia and New Zealand.
